Arc consistency look ahead also checks whether the values of x 3 and x 4 are consistent with each other (red lines) removing also the value 1 from their domains. A look-ahead technique that may be more time-consuming but may produce better results is based on arc consistency. Namely, given a partial solution extended with a value for a new ...
The sponsor may fund several studies at the same time, suppressing results found contrary to their business interests while publicizing the results that support their interests. Indeed, a review of pharmaceutical studies revealed that research funded by drug companies was less likely to be published, but the drug-company-funded research that ...
Studies which report a positive or statistically significant result are far more likely to be published than ones which do not. A counter-measure to this positivity bias is to hide or make unavailable the results in the paper, making journal acceptance more like scientific grant agencies reviewing research proposals. Versions include:
Due to the inundation of original research in the field, there is a need for review articles which highlight relevant studies, results and trends. [4] The varying methods and participants used among original research studies can provide inconsistent results, thereby presenting a challenge in synthesising information using one common metric.
Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method.For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.
The choice of how to group participants depends on the research hypothesis and on how the participants are sampled.In a typical experimental study, there will be at least one "experimental" condition (e.g., "treatment") and one "control" condition ("no treatment"), but the appropriate method of grouping may depend on factors such as the duration of measurement phase and participant ...
